BOOKMARKED
Many people suffer an allergic reaction to certain sulfites, including those that are commonly added to wine as preservatives. However, since there are several winemakers who add sulfites to none of the wines they produce, people who would like to drink wine but are allergic to sulfites can drink wines produced by these winemakers without risking an allergic reaction to sulfites.

Which of the following is an assumption on which the argument depends?

(A) These winemakers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine.

(B) Not all forms of sulfite are equally likely to produce the allergic reaction.

(C) Wine is the only beverage to which sulfites are commonly added.

(D) Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction.

(E) Sulfites are not naturally present in the wines produced by these winemakers in amounts large enough to produce an allergic reaction in someone who drinks these wines.


Edit: This is from ETS paper test, retired GMAT Q.


Note:
1. There is another question, which is almost same to this one, has only last two options interchanged. This particular question here is from OG and the official one. Other one, where option D and E are interchanged, might be from MGMAT.
2. Some people discussed on the OG question and some people discussed on the MGMAT question. Please observe the reference while reading through the thread.
[Reveal] Spoiler:
For OG, answer is E and for MGMAT answer is D -- text content of these two are the same though.

3. With the similar stimulus, there is a different question (weaken question) from GMAT Prep -- that is discussed in:

E) for me

Lets try to negate both A) and E)

If A) is not true then it still doesnt matter whether preservative effect is there or not in wine. Argument is more concerned about allergic sulfite.

If E) is not true then argument falls apart since sulfite present naturally will cause allergy not matter sulfite is added to wine or not.

Applying negation formula.

conclusion: people who are allergic to sulphates can,without a doubt, drink wine made by these guys

A) we are talkin about people who are allergic suphates ,not any other eliminated
B) negate it... all forms of sulphates are equally likely to produce allergy..These guys dont add sulphates. dont care...eliminated
C)we are talkin about wine only..eliminated
D)we are only concerned about allergy caused by sulphates..dont care about other substances.
E)negate it..sulphates are present in wines in amounts large enough to cause allergy ..even though sulphates are not added as preservatives...they are present...Correct

E

D for me.


The argument mentions "people who would like to drink wine but are allergic to sulfites can drink wines produced by these wine makers without risking an allergic reaction to sulfites".

This means, people will not get allergic reaction by drinking wines that do not have slifites. However, if such wines have other substances that causes allergic reaction, then the argument does not hold good.

Yeah, I chose D as well. It was really clear actually. You see, the argument made its conclusion so logically. There is no gap in its logic. Everything went smoothly from the premise to the conclusion. So our assumption here will not be required to fill a gap because we don't have any gap. The assumption we're looking for must attack any answer choice that could weaken the argument.

When the argument concludes that the lack of sulfites in wine will prevent people from getting any allergic reaction, we have a causal argument here. The causal here is that sulfites cause allergic reaction. Our assumption will attack any answer choice that could weaken this conclusion. In order to weaken this conclusion, an alternative cause to the effect can be raised. Our assumption must attack any alternative causal relation to this logic.

Option D, the assumption has attacked an alternative cause to the same effect. If this assumption is not true, then our conclusion will weaken the argument. so this is the correct answer.

I dont agree with D :

D says : Apart from sulfites, there are no substances commonly present i......

The argument starts : Many people suffer an allergic reaction to certain sulfites................

clearly here the argument is about the alergies specific to Sulfites ,, hence D cannot be the answer which talks about something apart from
sulphite.

E is the best for me .

Answer: D

Argument: people prone to sulfites allergic reaction can drink wines from makers who add no sulfites to their wines. Here an assumption is these people will not get allergic reaction from anything other than these sulfites or these special wines have no other substances’ that induce allergic reaction.

A. These wine makers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine. [What they duplicate is irrelevant – eliminate it]

B. Not all forms of sulfite are equally likely to produce the allergic reactions. [Argument is only concerned with special wines that don’t have any sulfite – eliminate it]

C. Wine is the only beverage to which sulfites are commonly added. [Argument is only concerned with special wines that don’t have any sulfite – eliminate it]

D. Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction. [Hold it]

E. Sulfites are not naturally present in the wines produced by these wine makers in amounts large enough to produce an allergic reaction in someone who drinks these wines [this contradicts the argument – clearly it is mentioned that they do not add any sulfites – eliminate it]

Which of the following is an assumption on which the argument depends?

A. These wine makers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine. -> no where in the argument we want preservative effeect of wine,again negate this ,argument is not affected

B. Not all forms of sulfite are equally likely to produce the allergic reactions. ->this does not help ,since argument says any sulfite producing allergic reaction will be harmful and if present in wine will be harmful

C. Wine is the only beverage to which sulfites are commonly added. -> people drink wine ,for those people this is the argument .this option is out of scope

D. Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction. -> we are not bothered about others !!!since only these sulfites are discussed

E. Sulfites are not naturally present in the wines produced by these wine makers in amounts large enough to produce an allergic reaction in someone who drinks these wines. -> THIS IS APT .negate this we get if sulfites present already then even if we drink wines from these winemakers we ll get allergy argument falls apart .IMO

Throughout the passage we are talking about people who are alergic to certain sulfites and how to help them go for wine in spite of wine
putting sulfites as preservatives .Hence even if we negate the particular argument is not changed ,since presence or absence of other allergic substances does not change their allergy to sulfite !!!

MAIN Conclution of the argument :
people who would like to drink wine but are allergic to sulfites can drink wines produced by these wine makers without risking an allergic reaction to sulfites.

HENCE E

E is best answer here. This is the defender assumption. If sulfites can be naturally synthesized during producing wine, the consumers may be affected by SULFITES.

D is not correct answer, we do not care about other substances, other than sulfites, that can cause allergic reaction.

D is my answer. It was not really stated whether preservative is the only source of the sulfite in the wine, it just stated that it qualifies as one.

However, since there are several wine makers who add sulfites to none of the wines they produce, people who would like to drink wine but are allergic to sulfites can drink wines produced by these wine makers without risking an allergic reaction to sulfites.

Which of the following is an assumption on which the argument depends?


Explanation:
--------------------
A.) These wine makers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine. ---> Not sufficient. Why?

It's clear from the option that they are not adding sulfites; they are actually using some non-allergenic substances, but what if sulfites are naturally present in wines? What if this quantity of naturally present sulfites in wine is sufficient enough to cause allergic reactions?

So, discard this option.


B.) Not all forms of sulfite are equally likely to produce the allergic reactions. ---> This does not say anything about wine produced by wine makers who do not add sulfites. Discard this too.


C.) Wine is the only beverage to which sulfites are commonly added. ---> Irrelevant. Moreover, use of extreme word only.


D.) Sulfites are not naturally present in the wines produced by these wine makers in amounts large enough to produce an allergic reaction in someone who drinks these wines. --->

To test if a statement is an assumption required for an argument, try to negate it. If the argument falls apart, it means the argument requires that assumption.

Here, if we negate option D, we get:
Sulfites are naturally present in the wines produced by these wine makers in amounts large enough to produce an allergic reaction in someone who drinks these wines.

It's quite clear that in view of the above statement, the conclusion will definitely fall apart.


E.) Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction. ---> This is wrong because we have to look for allergic reactions caused by sulfites only.

Just refer to the following parts in the excerpt: ...but are allergic to sulfites...without risking an allergic reaction to sulfites

whereas option E focuses on simply allergic reaction, NOT specifically allergic reaction due to sulfites.

Hence, I discarded this option.

For a moment, even if we assume it to be correct, it's still not as strong as option D.
--------------------

My choice is option D. Hope that helps.

This was a really good question reply2spg! I found option A really tough to reason. +1 to you.

Technext

- forms - OOS

C. Wine is the only beverage to which sulfites are commonly added.
- we are talking about wine only - OOS

D. Sulfites are not naturally present in the wines produced by these wine makers in amounts large enough to produce an allergic reaction in someone who drinks these wines.
- IMO -
E. Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction.
- Other substance in wine is OOS

The statements in the stimulus is confusing. But this looks like a pretty straightforward answer. Option E for me.
